This invention relates to a receptacle closure.

The general object of the invention is to provide an improved receptacleclosure for use on receptacles such as bottles and jars and wherein theclosure is of such a nature that it permits a fresh medicinal solutionto be prepared by operation of parts of the closure;

A more specific object of the invention i to provide a receptacleclosure including an inner and an outer member and wherein the innermember carries a distendable diaphragm which is adapted to be moved bypressure of the outer closure member to cause release of a tablet.

Another object of the invention is to provide a receptacle closureincluding a novel form of cap member wherein a flexible body has a stiffportion thereon which provides for quick preparation of a freshsolution.

Other objects and the advantages of my invention will be apparent fromthe following description taken in connection with the accompanyingdrawings, wherein:

Fig. l is a central, sectional view showin a receptacle closureembodying the features of my invention;

Fig. 2 is a view similar to Fig. 1 showing the closure in anotherposition, and

Fig. 3 is a fragmentary section taken on line 33, Fig. 1.

Referring to the drawing by reference characters, I have shown myinvention as embodied in a receptacle closure which is indicatedgenerally at Ill. As shown the closure is arranged on a receptacle whichincludes a body having a neck II and having an outwardly directed groove12 in the neck.

My closure, as shown, consists of an inner member, indicated generallyat I3, and an outer member, indicated generally at l 4. The inner memberincludes a flanged sleeve l5 which rests upon the end of a flange l 6 onthe container neck. A sealing band, which may be made of metal orplastic, is indicated at ll. The band ll engages the sleeve [5 and theflange IE to hold the inner member 13 in place.

The outer member includes a body 2|], having a downwardly directed skirt2| and having an enlarged flange 22 at the lower end of the skirt. Theflange 22 is removably received in the groove 12 previously described sothat normally the parts occupy the position shown in Fig. 1. The body 20is preferably made of a good grade of soft rubber and includes adepending, integral, tapering stem member 24 which is made of rubberwhich cures harder than the rubber of which the body 29 is 1 eel (01.128-272) made so that themember 24 does notflex readily and thereforedoes not bend when the closure is operated as will be later described.

The inner member sleeve l5 includes a loose diaphragm 3B which is moldedin corrugated form with the corrugations concentrically arranged as at3|. The diaphragm normally assumes the position shown in Fig. 1, withthe corrugations in their compact form and they are so vulcanized. Thediaphragm is soft and may be distended to the position shown in Fig. 2by pressure of the stem 24.

The inner member [3 is preferably made of a good grade of rubber andincludes an axial cavity 32 which communicates with a reduced cavity 33,coaxial with the cavity 32. The diaphragm 3!] serves as the upperclosure for the cavity 33 and in this cavity 33 I arrange a medicinaltablet 34. In the cavity 32 I arrange a displaceable sealing disc 35.The disc may be made of composition impervious to the contents of thereceptacle H).

In use the parts are assembled as shown in Fig. 1, with a vehicle forthe tablet 34 in the receptacle. To prepare and use the solution, theoperator presses on the body 20 so that the stem member 24 distends thediaphragm by straightening out the corrugations thereof, and pressure ofthe diaphragm pushes the tablet 34 towards the disc seal 35 to dislodgethe seal 35 and free the tablet, which may contain any suitable drug orpreparation. Thus the tablet is discharged into the vehicle 36 and afresh solution is prepared.

To use the solution the operator removes the cap I4 by stretching theflange 22 and thereafter a hypodermic needle is inserted through thediaphragm 30 and a sufiicient amount of the contents is removed to meetthe needs of the operator.

The diaphragm 35 is inert in the solution.

In the present application, Ser. 4,193, filed J an-- uary 24, 1948, theclaim is directed to the closure which includes a corrugated diaphragmengageable by a releasin stem carried .by an auxiliary closure.

In applicants copending application Ser. No. 791,429, filed December 12,1947, the claims are directed to a main and an auxiliary closure, with aflanged piercing member extendin through a hole in the auxiliary closureand movable with the auxiliary closure to displace a sealing disccarried by the main closure.

In copending application Ser. No. 791,428, filed December 12, 1947, theclaims are directed to a tubular disc displacing member wherein thetube.

3 is provided with a flange which is arranged within the auxiliaryclosure.

In copending application Ser. No. 4,089, filed January 24, 1948, theclaim is directed to the main and outer closures, wherein the mainclosure includes a cupped diaphragm portion and the outer closureincludes a stem which engages the cupped portion to cause release of asealing disc.

From the foregoing description it will be apparent that I have inventeda novel receptacle closure which is highly efficient for its intendedpurpose.

Having thus described my invention, I claim:

A closure comprising a main body portion and a flexible auxiliaryclosure portion, said main body portion having a flange adapted toengage the neck of a bottle, said body portion having a sleeve portionadapted to fit Within a bottle neck. said sleeve portion having an axialrecess, a sealing disc closing said recess, a medicinal tablet in saidrecess, and a diaphragm closing the inner end of the recess, saiddiaphragm having a cor- 4 rugation formed therein, said auxiliaryclosure including a body having a skirt thereon, said last mentionedskirt engaging the periphery of said body portion, said auxiliaryclosure having an inwardly directed integral seal releasing stem adaptedto engage and push said diaphragm to disc releasing position.
